Explanation

To bypass a Network Access Control (NAC) mechanism that uses MAC address filtering, the most effective technique is MAC spoofing. This involves changing the MAC address of the attacker's device to match an allowed MAC address on the network. By doing so, the penetration tester can trick the NAC system into granting unauthorized access.
